TRACTOR-W'HEEL.

To aZZ whom it may concern:

Be it known that I, Louis E. SLAUSON, a citizen of the United Statesresiding at ll iloline, in the county of Rock Island, and State ofIllinois, have invented certain new and useful Improvements inTractor-lVheels, of which the following is a specification.

My invention relates to traction wheels and consists in an improvedtread shoe and in its application to the traction wheel.

One object of my invention is the usual one present in auxiliary treadwheels of providing a large flat track for the support of the wheelproper. I desire to provide a simple device which may be attached to andremoved from various types of wheels even though the latter were notoriginally designed to be equipped with auxiliary tread shoes.

A further object is to attach my tread shoes to the wheel so that asthey are placed suc ccssively on the ground they will present their fullground engaging surface to the ground avoiding an angular or end-wisecontact of the shoe with the ground. This results in less compacting ofloose earth and in a smoother progression of the wheel. It also avoidsan undue strain on the shoe and enables the same to be made lighter andaccordingly more economically than if the shoe engaged the around oneend first and then. pivoting or that end moved into horizontal positionwith the advancement of the wheel. Also, when the shoe is lifted fromthe ground it is, at first, raised vertically, thereby avoiding plowingup the surface or scraping toward the wheel.

Referring to the drawings Figure 1 is a side elevation of a tractionwheel equipped with my tread shoe.

Fig. 2 is an enlarged side elevation of one of the auxiliary treadshoes.

Fig. 3 is a cross-section taken transversely of Fig. 2 along line 33 ofFig. 2.

Fig. 4 is a longitudinal section of the shoe taken along line l-4 ofFig. 3.

The wheel proper has a hub and a rim or telly 2 herein as a plain ironbandbut it will be. understood that my shoe may be applied to a varietyof rims differing substantially from the one shown.

A plurality of evenly spaced bearings 4 are secured to the innerperiphery ot the wheel rim and each tread shoe is adapted to 1. spokes 23, the latter being shown Specification of Letters Eatent.

'There has been herein shown ribed thepreferred embodiment o passing: heel will lati on to any earth which hasand de- 'f my invention, but changes can be made in the con structionand arrangement of the parts thereof, Without departing from the spiritof the same.

Vhat I claim and desire to secure, is: V

1.1-; traction shoe for attachment to the rim of a Wheel and comprisinga pair of parallel plates having lateral flanges, par allel transverseangle ribs spaced apart and connected to said plates on the bottom ofsaid flanges, and means for loosely connecting the plates to the wheelrim.

2. A traction shoe for attachment to the rim of a wheel and comprising apair of parallel upstanding plates having lateral flanges, transverseangle ribs spaced apart and con nected to said plates on the under sideof said flanges, blocks fastened to said plates and having openingstherein, and means engaging said openings for loosely connecting theshoe to the wheel rim.

3. The combination with the rim of a. wheel, of a traction shoecomprising a pair of parallel upstanding plates having outwardlyprojecting lateral flanges, transverse angle ribs spaced apart andconnected to said plates on the under side of said flanges, blocksconnected to said plates on the upper side of said flanges and havingelongated openings therein, a bearing block fastened on the inner faceof the wheel rim and having a bolt opening therein, and a bolt seated 1nsald openlng 1n the bearing block and engaging said elongated openings.

i. The coniblnation with the rim of a wheel, of a. traction shoecomprlsing a pair of parallel upstanding plates having out,

wardly projecting lateral flanges, transverse ribs spaced apart andconnected to said plates, on the under side of said. flanges, blocksmounted on said plates on the upper side of said flanges andhaving-elongated openings therein, the upper portion of each openingbeing wider than the lower portion thereof, a bearing block fastened onthe inner face of the wheel rim and having a bolt opening therein, and abolt seated in said opening in the bearing block and engaging saidelongated openings.

In testimony whereof I aflix my signature.
